Perimeter Action Ships are part of a unique military strategy
used against both the Klingons and Romulan during many of the early conflicts.
Perimeter Action Ships were designed to use stealth and heavy firepower to
engage enemy vessels during times of war.
Most Perimeter Action Ships do not have the extensive crew
facilities found on other Destroyer vessels, often being on patrol for no more
than 6 months. Perimeter Action Ships are smaller than a standard Destroyer, but
have similar mass. Perimeter Action Ships use even more specialized and stealthy
sensor systems, and are designed to be mass produced easily. Most Perimeter
Action Ships do not have the research capability of a Destroyer, and rarely have
shuttle bays, extensive repair facilities or emergency systems. Perimeter Action
Ships do mount a large number of redundancy systems, giving them more resilience
Although easy to mass produce, Perimeter Action Ships are
surprisingly expensive, often costing twice what a standard Destroyer costs.
This, coupled with their limited exploration capability has kept their numbers
reduced. But their heavy firepower and other unique systems continue to create a
niche not filled by a standard Destroyer.
